Steps to reproduce:

I opened https://www.pcgameshardware.de/God-of-War-2018-Spiel-57369/News/Bewertung-Steam-Patch-101-Sensationeller-Port-1387299/amp/

Actual results:

The page has a navigation bar that opens and overlaps the main page in a weird way.
It's not just a broken script, that doesn't allow the sidebar to be closed.
Some text and images clip through the navigation bar (like wrong z-values)

Expected results:

This doesn't happen in Beta nor Nightly nor Chrome.
It has been happening for months on the amp variant of PCGH.
I verified before that it was fixed in Nightly. Later on in Beta. But since I kept on getting this issue I decided to verify last december:
Not happening in Nightly 97, Not in Beta 96.
But now that 96 was released it's still there.

So this bug is only appearing in the release for some reason.

It might be partially due to tracking protection.
If I disable TP, then it's still not fixed, but then I reenable TP and reload the page and suddenly the sidebar stays closed and I can open and close it without the z-index issues. Which is weird.
It's only fixed when TP is "on".

Up until today my fix was removing "amp/" from the end of the URL, since this bug only happens in the amp version of the page.

If someone could please take a look at this, that would be great :)
There have been several issues on webcompat, but they only blame disabled scripts from tracking protection. But why is it only fixed after toggling TP and leaving it on? Doesn't make sense to me.

This showcases, what I'm seeing

The Bugbug bot thinks this bug should belong to the 'Core::Privacy: Anti-Tracking' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Component: General → Privacy: Anti-Tracking

According to comment 0, this doesn't look like a TP issue because the page only works when TP is on, which is weird. I will reset the component back so that this bug can be triaged correctly.
